A roll cage design must comply with the MSA/FIA technical regulations published in the MS UK Blue book. It is the competitor’s responsibility to ensure his/her roll cage complies with the technical regulations appropriate to the event they are competing in.
To obtain a certificate for a self-fit roll cage, the installer must complete a Custom Cages weld test. Custom Cages’ roll cage kits include a weld test sample. Once completed these are returned to the company for load testing. They are subjected to a physical test to assess the actual yield strength of the weld. This ensures that the self-fit roll cages achieve the highest standards of integrity. Additional samples may be requested, and Certificates will only be issued on completion of a successful test.
Please be aware that there is a charge of £60.00 + VAT for all MS UK / FIA Certificates
